SUPPORTING MEANS non SPINDLES IN srinnine MACHINES AND THE LIKE.

This invention has reference to supporting means for the spindles ofslubbing, roving, spinning, twisting and similar machines, and .itrefers in particular to a novel construction of the supporting orjournaling beam for the reception and journaling of a plurality ofspindles of the kind mentioned, and among other objects and advantagesthe invention makes provision for a better lubrication of the spindlesand to generally improve the j ournaling and mounting of the same. Inthe slubbing, roving, spinning and twisting machines, asheretoforeconstructed the journals of the spinning spindles which werecommonskew wheels, were arranged inseparate'boxes or casings in such amanner that each spindle was provided with a journaling box of its ownand which was securedto the supporting beam. It has already beensuggested heretofore to mount all the different journaling andsupporting members in a sheet metal boi; in

which the operating shaft with the supporting means for the worm wheelswas arranged, and in which the rods for the raising of the ring bealnhadto be mounted by means of special additional bearing and retainingmembers. With these previous arrangements there was the inconveniencethat the exactness of adjustment of the entire supporting means wasinterfered with, and on the other hand there was but very imperfect irrotection against the escape ofv oil and the entrance of impurities; norwas the lubrica- 'tion of the spindles and of the gear wheelssatisfactory.

Vith a view of'overcoming these drawbacks the supporting beam inaccordance with my invention constitutes a closed casing for a pluralityof spinning spindles and provided with a continuous depression for thereception of the bottom journals of the several spindles and filled withoil, so as to provide for a very perfect lubrication and for an exactgearing of the spindles. Theboi: shaped beam is preferably constructedso as said bearings being arranged and adjusted in such a manner astoprevent the escape of oil from the casing to the outside. The meansfor the raising of the lifting rods ofthe ring beam passthrough thecasing in such a manner as to'be out of contact with the lubricatportingly operated by means ofworm wheels or to serve at the same time as ameans of mountmg the bearings for the driving shaft, the 6 ing space. Inaccordance therewith the sup and ournalingbeam is so arrangedApplication filed December 8, 1923, Serial No. 679,479, and in GermanyJu1y,14, 1923.':

and constructed that the fastening means for the several parts do notproject outwards through the bottom portion, while on the other hand thebeam serves asa carrier in common to all hearings or journals or ofother means which are directly supported or guided in the box-shapedbeam without any additional supporting members.

An embodiment of the principles of my invention is shown by wayofexample on the accompanying'drawing in which Figure 1 is a transversesectional view through the boxshaped beam, and FigureQ' is a horizontalsection through the same." I

y The supporting beam comprises a U-shaped I casting 1 theopcn side ofwhich may be closed bya slide or by a glass plate 2 tightly securedthereto by screws or otherwise. I i

di ithin the housing 1 a plurality of spindles 3fis supported by lowerball bearings 4 and upper ball bearings 5. The bearings 5 aretransversely held by springs 19 arranged in a casing which comprises acollar 7 atheight ofthe depression 8, so that the gear- Iingof thespindle isonly very little immersed into theoil, while when running thespindle aropels the oil upto the gearingof the worm wheel orthe like 10.T he'bearings 11 for the shaftlQ of the wheels 10 should be carefullyadjusted, inorder to produce smooth running of the machine With this endin view the bearings are supported by screw threaded studs 13 by theintermediary ofv a groove 14, the bearing being forced against the studby the drip-lubricator 15. It is of importance in" this connection thatthe holes 16 for the reception oft-he stud 13 in the casing 1 do notextend through the walls of the casing, as otherwisethere would be animpossibility of'tightening the casing against leakage of oil.

The so. called poker rods 17 on which the usual ring'rail is mountedWhich carries a spinning ring for its spindle are guided in;laterallugs'lS of the wall of the housing]. so as to preclude anycontact of the rods with the lubricant being within the lubricatingchannel. These ringrailsare well known to those familiar with the artand have thereof not been illustrated in the drawing. The invention hasbeen described in its broad aspectsand a plurality o1 spaced lubricantcavities communicating therewith at their upper ends,

a'plurality of spindles supported in and by the said casing, actuatingWOEIHS on the said spindles extending into thesaid lubricant channel andbeing adapted to lift lubricant therefrom upon lJeing rotated,aplurality of worm gears engaging with the spindle actuating Worins at apoint supplied With lubricant from the said channel by and upon rotationof the said spindles and being aii'anged at sucha level as to be out ofcontact with the lubricant that may he on the said bottoinwall, asupporting and actuating shaft for the said wvoi'in ears ii menresilient beaiings'for the t 7 L h saidspindies an lower spindlehearings at the unctions of the said lubricant channei end the saidlubricant cavities substantially as for the purpose described.
